Abstract

L'invention concerne un système de traitement de gaz d'échappement qui comprend: une unité de désulfuration (15) pouvant éliminer tout oxyde de soufre d'un gaz d'échappement (12) déchargé d'une chaudière (11); une colonne de refroidissement (16) disposée sur un côté flux de distillation de l'unité de désulfuration (15), qui peut éliminer tout oxyde de soufre résiduel dans le gaz d'échappement et abaisser la température du gaz; une unité de collecte de CO2 (17), qui comprend une colonne d'absorption pouvant amener le CO2 présent dans le gaz d'échappement au contact d'une solution d'absorption de CO2 pour éliminer le CO2, et une colonne de reproduction qui peut libérer le CO2 de la solution d'absorption de CO2 pour recueillir le CO2, et peut reproduire la solution d'absorption de CO2; et une unité électrique de collecte de poussières par voie humide (25) qui peut éliminer toute substance génératrice de brouillard, laquelle substance génératrice de brouillard est une source de génération de brouillard présente dans la colonne d'absorption de l'unité de collecte de CO2 avant introduction du gaz d'échappement dans l'unité de collecte de CO2.
